Our earth is going to be engulfed by the sun eventually. Urged by a primitive desire to continue life (human or not), I decided to devote my life to the said goal. I realised this is a risky, life-long endeavour with huge chance of achieving little at best. What is the best strategy for me? Should I become a scientist to invent discover new technology, or should I become CEO of a corporate-nation and then invest hugely on space exploration? Or should I become a head of state in order to mobilise resources of national scale? Or something else? From a utilitarian standpoint, which way is optimal?
